Wil y- 100000 I I '4 LAURITZ A. GUNST, OF OMAR, WEST VIRGINIA..

: s'rATEs PATENT oFFro STRAINER on SEPARATOR.

To all whom it may concern:

Be it known that I, LAURITZ A. GUNs'r, a subject of the King of Denmark,residing at Omar, in the county of Logan and State of (Vest Virginia,have invented new and useful Improvements in Strainers or Separators, ofwhich the following is a specification. 1

This invention relates to a strainer or separator especially adapted foruse -in the water service systems and sanitary pipes or lines ofsteamships, but which is susceptible of use in other similar systems,the primay object of the invention being toprovide a separator forarresting and prevent. ing the passage into the system of foreign vsubstances ofany material size liable to give trouble.

A further object of the invention is to provlde astrainer or separatorwhich 1s simple and lnexpenslve of constructlon, re-

. liable and eflicient in operation, and capable outlet 13.

of being readily and conveniently cleaned.

I The invention consists of the features of construction, combinationand arrangement of parts hereinafter fully described and claimed,reference being had to the accompanying drawing in which:-

' Figure 1 is a verticallongitudinal section I through the device.

Figure 2 is a vertical transverse sectionon I the line 22 ofFigal.

In carrying my invention into practice, I' provide a strainer orseparator compris- I ing a substantially oblong rectangular casing orshell 1, having at one end an inlet. 2 and at its opposite end an outlet3,'said. inlet and outlet being threadedfor connection withpipe sectionsbetween which the device is practice'arranged and being located inproximity to the lower portion of said casing. The casing is open at'thebottom and closed by a base plate 4 Which is detachably secured inposition by screws or other suitable fastenings 5, the construc-' .tionbeing such as to provide for the ready removal of thebaseplate whenoccasion is required to clean the "device or repair orv renew any of itscontained parts. f

The ca ing is provided at a point about intermediate of its length witha vertical transverse baflie plate 6'separating said -c asing intoprimary and secondary chambers 7 and 8, which chambers are in directcommunication respectively wi'th the inlet and Specification of LettersPatent.

I The baflieplate 6 extends entirely across Patented Feb. 6,1917.

Application filed June 23, 1916. Serial No. 105,479. I Y

the casing but terminates below the top of the casing to provide apassage-way 9 connecting the chambers 7 and 8 at their upper portionswith each other. The baflie' plate 7 is preferably carried by andintegral with the base plate 4, and said base plate is provided with'adepending chamber 10 forming a pocket or trap communicating with thebottom portion ofthe primary'chamber 7 and arranged below the level ofthe in let 2. The side walls of the casing are provided with groovedguideways'll to receive a perforated strainer plate 12, which strainerplate rests upon and may be carried by the bottom wall 4. The strainerplate is dis posed between the outlet 3 and baflie 6 and extends thefull depth of the chamber 8..

The holes in this strainer plate are comparatively small in diameter,not exceeding onefourth of an'inch, and are sufficient in numher toallow a surplus of area'of the holes of at least 50% above the area' ofthe fluid supply pipe, thus providing for the free passage of the fluidat all times, notwithstanding the fact that a .comparatively.largeamount of matter may be caught and retained by the strainer.

In the use of the device, it is placed in the pipe". line'close to thewater circulating pump, the water entering at the inlet 2, passing'into.the pocket 10' and chamber 7, thence-flowing through the passage 9 intothe..chamber- 8 through 'the screen 12, and

finally dis Charging through an outlet 3'to the water'sup'plysystem'forcirculation. On

" its admissionginto the separator the water strikes against thebafli'efi, which forms a dam, whereby all rocks, gravel,"mussels,, etc.,

are st'oppedin the-course of flow and caused to fall'by 'gravity' intothe pocket 110,- the water then flowing over the I bafliefi'and outthrough the separator aisb'eforeidescribed. 7 Any seaweed .orotherlighter matterwhicli may pass over the bafile with the water will jstrike against and be retained'b'y the screen, whereby the water. willbe'freed from all solid or large particles of matter liable to givetroubleand the circulating system kept clear thereof.

From the": foregoing description, taken'in connection "with the drawing,the construc tion, mode of operation and advantages" of my improvedseparator will be readilyun derstood. -When the device is to be cleaned,which must be done at intervals, it will be understood thatv this may beeifected by removing the fastenings 5, whereupon the bottom plate 4 willdrop down with the screen 12 and may be entrapped within the separator,permitting the work to be readily and conveniently performed.

I- claim 1. A separator of the character described comprising a casinghaving an inlet and an outlet, located at opposite sides thereof, saidcasing being provided with a detachable bottom portion having adepending pocket or chamber located at its side adjacent to said inlet,a screen extending the full depth of the casing and arranged betweensaid pocket or chamber andthe outlet of the casing, and an imperforatebafile plate fixed to the detachable bottom between the pocket orchamber and the screen, said plate extending from the detachable bottomupwardly to a point below the top of the cas- 2'. A separator of thecharacter described comprising a casing having an inlet'and an outlet,located at opposite sides thereof, said casing being provided with adetachable bottom portion, said detachable bottom portion being providedwith a depending pocket or chamber and a baflle plate extending upwardlyinto said casing to a point below the comprising a casing having aninlet and an outlet, located at opposite sides thereof and provided witha detachable bottom, a. baffle fixed to the detachable bottom andextending upwardly into said casing between the inlet and outlet, and ascreen fixed to the detachable bottom and slidably engaging the casingbetween the bafiie and outlet.

4. A separator of the character described comprising a casing having aninlet at one side thereof, an outlet at the opposite side thereof, adetachable bottom plate closing thebottom of the'casing, said platehaving a depending portion forming a trap or pocket adjacent to saidinlet,'a bafiie plate rising from'the detachable bottom between the trapand outlet and terminating below the top of'the casing, and a screendisposed within the casing between the'bafile and outlet, said screenslidably engaging the, casing so as to be held in position by the bottomplate and being movable with the latter.

In testimony whereof I afiix my signature.
